This invention discloses a method for preparing high-performance wood wax oil, belonging to the field of coating technology. The raw materials used in this wood wax oil are soybean oleic acid, maleic anhydride, grafting catalyst, glycerol, phthalic anhydride, esterification catalyst, vanadium drier, zirconium drier, carnauba wax, and beeswax. Compared to wood wax oils based on tung oil and linseed oil, the wood wax oil of this invention uses soybean oleic acid as the main material, utilizing maleic anhydride to perform graft copolymerization at the α-position of the carbon-carbon double bond in soybean oleic acid, thereby increasing the iodine value of the resin system. Increased iodine value leads to increased crosslinking points, thus ensuring drying properties and improving the hardness, drying performance, and yellowing resistance of the wood wax oil; weather resistance is significantly improved, and drying time is accelerated; no heavy metal driers such as cobalt and manganese are added, making it environmentally friendly; the preparation process of the wood wax oil of this invention is simple and easy to operate, with low material costs.

The present application relates to the technical field of composite functional materials, in particular to a spinel-type composite photothermal super-hydrophobic coating, a preparation method thereof and application thereof in ice prevention and removal, wherein the preparation method of the spinel-type composite photothermal super-hydrophobic coating first prepares spinel-type CuFeMnO4 material with micro-nano structure through co-precipitation and high-temperature heat treatment of copper salt, iron salt and manganese salt, and then performs surface hydrophobic modification on the spinel-type CuFeMnO4 material by using palm wax. By combining the excellent photothermal conversion performance of the spinel-type CuFeMnO4 material with the low surface energy characteristics of palm wax, the synergistic effect of high-efficiency photothermal conversion and super-hydrophobic performance is realized, so that the coating layer formed by the prepared spinel-type composite photothermal super-hydrophobic coating has excellent super-hydrophobicity, durability and environmental adaptability and can achieve good ice prevention and removal effect. In addition, the preparation method has the advantages of simple process, low cost and environmental friendliness.

This invention discloses an emulsion gel based on a compound of carnauba wax and monoglycerides, and its application in bread making as a substitute for margarine. The emulsion gel uses high-oleic sunflower oil as the base oil, with carnauba wax and monoglycerides compounded in a mass ratio of 5:5-8:2 as the gelling agent. Soy lecithin is added, and the mixture is pretreated by microwave, dissolved by heating, dispersed by ultrasound, and refrigerated to obtain the oil gel. Deionized water is then added, followed by homogenization, ultrasound, and refrigeration. The resulting emulsion gel completely replaces margarine and is used with high-gluten flour, water, sugar, and other ingredients to make bread through kneading, proofing, and baking. The synergistic effect of carnauba wax and monoglycerides through complementary HLB values, synergistic crystal structures, and intermolecular interactions solves the problems of excessive hardness and poor stability associated with single gelling agents. The bread prepared by this invention has zero trans fatty acids and low saturated fatty acids, a soft and fluffy texture, and sensory quality comparable to commercially available margarine bread. The process is simple and has broad application prospects.

The invention relates to a method for preparing a biomaterial for the treatment of skin cancer, based on the exoskeleton of the scorpion Tetratrichobothrius flavicaudis. The method consists of several steps: 1) extracting the exoskeleton from a dead scorpion, 2) roasting at 250°C for 30 minutes to remove moisture and enhance the stability of the material, 3) grinding the roasted exoskeleton to obtain a fine powder, 4) sieving the powder to 0.5 mm to homogenize the texture. Then, 5) the powder is mixed with vegetable oil (olive or argan) in a ratio of (1:5 w / w), 6) carnauba wax is added to obtain a solid consistency, 7) the mixture is heated to 45°C and then cooled to form a solid paste. This biomaterial has biocompatible, anti-inflammatory and healing properties, suitable for the treatment of skin cancers.
